Applica tion filed June 8,

To rill to 7mm it may concern,

Be itknown that I, l'ViLLraii ltonnnn, a citizen of the United States, residing at l/Vhite Plains. in the county of ld estchester and i ltate of New York, have invented certain new and useful Improvements in Embroidery Frames, of which the following; is a full, clear, and exact specification.

This invention relates to embroidery frames especially designed for use on embroiderinomachines. This application is a continuat on in part of an application filed by me on July 23, 1920, flerial No. 398,337, patented. Dec. 13, 1921, No. 1., l00,293.

it is the aim of the present invention to provide an embroidery frame of improved construction forholding the fabric to be embroidered in proper position during the embroidering thereof by a machine. The frame is also especially adapted for use on a design positioning device, such as is disclosed in my above mentioned application, so that the de sign to be embroidered on the fabrics held by a plurality of frames may be uniformly arranged thereon.

Another object is to provide a frame consistinp; of fabric clamping members which are adapted to firmly hold the most delicate fabrics between them without injuring the same. .r-l further object is to provide means for quickly clamping: the members of the frame together and releasing them. when de sired, means beinpg'also provided. for automatically separating said members, as soon as they are released, in order to permit ready access to the fabric for adjusting or removing the same. Still another object is to pro vide the frame with means for supporting a roll of fabric while the end portion thereof is clamped in the frame. The invention will be further hereinafter described in connection with the accompanying drawings, which. constitute part of this specification, and then more specifically defined in the claims at the end of the description.

In the accompanying drawings, wherein similar reference characters are used to designate corresponding parts throughout the several views:

Figure 1 is a side view of an. embroidery frame constructed substantially in accordance with this invention, the clamping members thereof being shown inseparated position.

The f" me comprises complemcntal clamp ingmembers or jaws .l. and 2 which are hinged at one end by pivot pins 8, Figs. 1 and The member 1 is formed with a rectang'ular channel in its upper face consisting of lonc' tudinal channels 5 and conimuni cat as channels 6. while the member ,4 has a correspondingly arrangedrectano'ular rib proiectin from its lower face and consisting); of lon, vrudinal ribs 13 connected to transversev ribs Said rectangular rib on the member 2 registers with the rectangular groove in the member 1 so that when said member 2 is swung downward into en agement with said. member 1, said rib will be inserted into said groove, as shown Figures 2and Longitudinal grooves 5 and corresponding ribs 13 are preferably extended some distance beyond the transverse grooves 6 and ribs 14-, as best shown in Figures 4. and 5, in order to more firmly the fabric 30 without danger of tearing or otherwise injuring the same. Said. fabric is preferably cushioned between a suitable lining 27 in the rectangular groove of the member 1 and a similar covering 28 on the rectangular rib of the member 2, as shown in Figure 7-. V

In order to save metal, the members of the frame are made in skeleton form, as shown, with a cross bar 8 at the free end of the member 1 and a corresponding cross bar 16 at the free end of the member 2. A pair of spaced lugs 19 extend from the central.

portion of the cross bar 16 longitudinally of the frame member 2, and between said lugs a locking lever l is pivoted at 26, said lever having a hook-shaped end 23 to engage below the cross bar 8 of the frame member 1 when the member 2 is engaged therewith. llhe hook-shaped end 23 of the locking lever el preferably covered with cushioning sectional view Figure terial 24, as shown in Figure 2, to further protect the goods and to eliminate the noise of contacting metal parts. Said lever is yieldingly pressed into locked position by a spring 260 supported between lugs 21 on the upper face of the cross bar 16 and having its inner extremities anchored in a slot 18 in said'cross bar. The free end portion 25 of said spring 260 is preferably bent at an obtuse angle with the main portion of said spring, as shown in Figure 2, in order to more eii'ectively bear upon the lever 1.

The pivoted end portion of the frame member 2 is formed with arched portions 17 reinforced. by ribs 20 on their outer faces, to permit a roll of fabric 80 to be carried bctween said member 2 and the member 1. of the frame when said members are in engage ment with one another, as illustrated in This arrangement permits the end portion of a roll of fabric to be cl'an'iped between the ribs and grooves of the members of the frame without being severed from the rolhand provides convenient means for supporting said roll so that it may be carried along with the frame during the design )ositionin and embroiderin operations."

To automatically separate the members of the frame when they are released, a spring 22 is mounted around the pivot pins 3 connecting said members, as best shown in Figure 1, said pins 3 connecting the end portions 15 of the arches 17 of the member 2 with pairs of lugs 12 arranged in line with the'side walls of the grooves 5 of the member 1. A cross bar 7 preferably extends between'the spaced end portions of said member 1 bearing the lugs 12, and said cross bar may have a perforation 9 therein for engagement with a bolt or other holding means (not shown) for fastening the frame rigidly in place during the embroidering operation.

The free end of said. member 1 is prefer ably provided with downwardly extending lugs 10 having notches 11 therein for engaging a rail or guide (not shown) of a design positioning device or embroidering machine. The cross bar 8 at the free end of the frame member 1 may also be perforated at 9 to receive suitable holding means for fastening the frame rigidly in position while the fabric clamped therein is being embroidered.

I claim:

. 1. An embroidery frame comprising interengaging clamping members having extensions hinged together at a distance from the clamping portions, one of said extensions being offset from the other providing storage space for a roll of fabric between said extensions while a portion of said fabric is clamped in the frame.

2. An embroidery t'ramecomprising interengaging clamping members, one member having a groove and the other member having a rib to fit said groove, said members having extensions hinged together at a distance from their grooved and ribbed portions, and one of said extensions being offset from the other to provide storage space for a roll of fabric between said extensions while a port-ion of said fabric is clamped between the groove and rib of said members.

embroidery frame comprising interengaging clamping members hinged together at one end, and a locking lever on the free end ofone member for releasably engaging the other member, said lever having a hook-shaped end covered with cushioning material for the purpose specified.

In testimony whereof I have signed my name to this specification.

WILLIAM KOLLER.
